Police said they received reports of suspicious drug activity near an apartment building on Picket District Road. When officers responded, 20-year-old Christian Giragosian, of New Fairfield, attempted to flee, police said, but was taken into custody.

Police said Giragosian had four active warrants for his arrest with bonds totalling more than $70,000. He was charged with interfering with an officer for Thursday's incident as well as failure to appear in court and a violation of probation.

While police initially said Thursday afternoon the kindergarten through third-grade school was under lockdown, schools Superintendent JeanAnn Paddyfote said officials were preparing for a lockdown when they received word that a suspect was in custody.

"At approximately 1:54 p.m., the principal at John Pettibone Elementary School received notification from the school resource officer that the New Milford Police Department wanted the school placed in lockdown because a person, possibly armed, was in the vicinity of the school," Paddyfote said. "Within moments, as the principal was initiating the lockdown, she received word from the resource officer that the person was in police custody and the situation was under control.

Giragosian was held on Thursday and is expected to be arraigned Friday in state Superior Court in Bantam.
